LOCKING DEVICE F03 AUTOMGBILES.

Application led March 5,

To aZZwho'm. it'ma concern.'

Be it known t' at I, DE WHT CLINTON SEE, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Locking Devices for Automobiles, of which the following is a specification.

The object of this invention is to provide a new and useful locking device for lockin the wheels of an automobile or other ve icle. This and. other objects of the in vention will be fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

'In the accompanying drawings, Figure 1 is a diagrammatic view of the locking device as it will appear when attached to the front wheels of an automobile. Fig. 2 is a sectional View of one of the locking bolts. Fig. 3 is a sectional view of the lock used in connection with `the locking device.

In the several figures like reference numerals indicate like parts.

In the drawings l indicates the front axle of'an' automobile on which are supported in the usual manner the wheels 2. `Rigidly fastened to this axle in any suitable manner near the outer ends thereof are thecylinders 3 and 4, inside of each of which are mounted to slide the locking pins or bolts 5. These bolts are made up of a pin 6 having a sleeve 7 on one end thereof into which projects the rod Shaving a shoulder 9 thereon. Interposed between the rod 8 and the end of the sleeve 7 is a compression spring 10 which normally forces the pin 6 into the position shown in Fig. 2. Passing through the rod 8 as shown in Fig. 2, is a small pin 11 whichprojects into suitable slots 12 provided in the sleeve 7 t-o guide and hold the pin 8 in itsproper position. interposed between the front end of the cylinder 4 and the shoulder 9 of the rod 8 is a compression spring 18 which normally holds the locking bolt 5 in its retracted position as shown in Fig. 2. Fastened to the rod 8 and forming al continuation thereof is the rod 14 having the 'forked end 15 on the outer endthereof.

Pivotally mounted on the\bearing plate 16 fastened to the body of the automobile is the lever 18. riChe lower end of this lever is connected to the horizontal bar 21 whih bar is mounted to slide in the stirrup or guide 22 provided on the frame of the ear.

The ends of the rods'let are connected to the end of the horizontal bar 21 by the links 23 and 24.

When the driver of the car Wishes to lock his car he operates the handle or lever 18 in the direction shown by the arrow in Fig. 1. This moves the bar 21 forward and forces the boltsl 5 outward, projecting them into the path of the. spokes of the wheels. lf .the driver wishes to unlock the car he moves the handle in the reverse direction which will cause the bolts to withdraw from the spokes and allow the wheels to turn.

To hold the bolts 5 in place between the spokes of the ,wheels I provide the following mechanism: Fastened to the dash board of the car is the lock 23A. This lock consists of a casing 24A in which any one of. the well known type of locks may be mounted. Operated by this lock 'through the crank 25 which is keyed to the end of the barrel thereof is the locking bolt 26. This locking bolt has a pin 27 fastened thereon which engages with the slot 30 on the end of the crank 25. 'Passing through the vlock easing 24.-A is a bar 31 having ratchet teeth 32 cut in on'the lower side thereof. The bolt 26 normally projects between these teeth 'and is held in engage,- ment between them by the compression spring 33. The bar 31 is pivotallyY mounted on the lever or handle '18 with which it moves when the handle is operated. The ratchet teeth ofthe bar 3l and the locking bolt 2G are so formed that' the lever and Patented. New. 2s, isis.

bar may be moved in but one'direction without operating the lock 23A. As shown in Figs. l and 3 the teeth of the bar 31, when moving to the right will depress the locking bolt 213 againstthe compression spring 33 andnllow the bolt to spring back in the consecutive teeth as they vpass the bolt which 'prevents the bar from moving in the reverse direction. To allow the bar 31 and lever 18 to move 1n the reverse direction Vthe lock 2l^ is operated which forces the easing this purpose the endl of each o1 the boits is made yieldable as shown in Fig. 2, so that they bolts must be thrown their full length before the lock will be active, in case the wheels of the car are not parallel with the body of the cer the bolt on one side may encounter a spoke of the wheel on that side by which its forward movement would be arrested. 1f the bolts were both rigid the forward movement of both might be arrested. Each bolt is, however, yieldingly mounted so that both can engage with their respective wheels simultaneously and so that the failure of the one bolt to' engage will not prevent the other bolt from en- As shown in Fig. 2 'the bolts 6' forced back until the shoulder Q may be engages the end of the sleeve *Z when the forward movement of the rod and bolts G will be simultaneous and positive.

It will be noted that this lool: is absolutely ositive and can be operated very convenlently by the driver of the car without leaving vhis seat and' to prevent'the bolts from marring the e okee of the wheels each of the bolts 'may e provided et its4 end with a soit rubber cap.

I claim:

1. In a locking device for automobiles the combination of an axle, wheels mounted to swing thereon, said Wheels having spokes,

:t pair ci cylinders rigidly mounted to said ae, e, bolt yieldsbly mounted in each of said cylinders, a piston rod slidebly conneet/ed to' each oi seid bolts, a compression spring interposed between said bolt and seid piston rod, Ineens to move said piston rod in and out of said cylinders and move seid bolts into and out of engagement between said' spokes of saidwheels.

2. In a locking device for automobiles the combination of an eine, wheels mounted to swing thereon, said wheels having' spokes, a pair of c linders rigidly mounted to said axle, n yie'dable bolt mounted to slide in each of said cylinders, a piston rod slidably connected to each oi said bolts, a compression spring interposed between said bolts and said piston rod, a shoulder on said piston 1od,'a compression spring mounted between said shoulder and the Walls of said cylinders, means to move said pist-on rods in and out of said cylinders and move said bolts'into and out of .engagement between seid spokes of said wheels.
